Confession of FaithChapter 1: Of the Holy Scripture

All things in Scripture are not alike plain in themselves, nor alike clear unto all:1 yet those things which are necessary to be known, believed, and observed for salvation, are so clearly propounded, and opened in some place of Scripture or other, that not only the learned, but the unlearned, in a due use of the ordinary means, may attain unto a sufficient understanding of them.2

1. 2 Peter 3:16

   as he does in all his letters when he speaks in them of these matters. There are some things in them that are hard to understand, which the ignorant and unstable twist to their own destruction, as they do the other Scriptures. (ESV)

2. Psalm 119:105

   Your word is a lamp to my feet
   and a light to my path.

   Psalm 119:130

   The unfolding of your words gives light;
   it imparts understanding to the simple. (ESV)
